What is the ratio between the mass of the part above the sea level and the mass of the part below
the sea level?

Answer is 1/7 to 1/6

I was not able to arrive at this answer..Please help

take the ratio of the lower limits and the upper limits

1/8th of iceberg above sea level=> 7/8 below sea level
1/7th of iceberg above sea level=>6/7 below sea level

ratio of above sea level to below sea level: (1/8)/(7/8) and (1/7)/(6/7)
=>1/7 and 1/6
